It happened in 1997 I think with LSU - Bama. They played 3 regular season games, 1 SEC Championship Game and in the National Championship Game.

If it ends up LSU-Vandy in the National Championship game, even though they are both in the SEC, it is possible that it would be the first time they have played each other in 2013 (if one of those two teams don't make the SEC Championship game).

Just my opinion but I think the NCAA will do anything if can to avoid an all SEC final in Omaha - their thinking being the country is tired of the SEC winning everything...even though we have the best athletics.
